Alfred Tauber

Alfred Tauber was a mathematician born on 5 November 1866 in Pressburg, now Bratislava in Slovakia, who died on 26 July 1942 in the Theresienstadt concentration camp. He studied at the University of Vienna from 1884, took his doctorate there in 1888 with Gustav von Escherich as his adviser, and began lecturing as a privatdozent in 1891, but he was long denied a professorship and earned his living as head of mathematics at an insurance company in Vienna. His research was on function theory and potential theory. In 1897 he stated the conditions, now called Tauberian conditions, under which a converse of Abel's limit theorem on power series can be proved, and the name Tauberian theorems was later coined by Hardy and Littlewood. He also contributed to the mathematics of insurance. The Nazis sent him to Theresienstadt on 28 June 1942 and he was murdered there.
